Application filed July 7, 1922. Serial No. 573,371.,

T 0 all whom it may concern:

' Be it known that I, JACOB KAUFMANN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inPile-Forming lVires for Pile-Fabric Looms, of which the following is aspecification.

My invention relates to pile forming wires for pile fabric looms of thetype wherein a plurality of the pile forming wires extend through thereed in a direction parallel to the warp threads and which are soarranged as to be controlled by means of heddles to which the wires arepivotallyconnected, this arrangement being provided for the purpose offorming patterns of the piles or loops in the fabric.

The principal object of my invention is to provide a novel form of pileforming wire. and controlling heddle which will be simple inconstruction and efficient for its intended purpose, which willbecharacterized by the absence of projecting parts on the side sur-'faces of the heddle whereby the warp threads may freely pass withoutinterference during the formation of the sheds, and which is furthercharacterized by the provision of a large bearing surface for thepivotal connection between the pile forming wire and its controllingheddle.

The nature and characteristic features of my invention will be morereadily understood from the following description, taken in connectionwith the accompanying draw ings forming part hereof, in which Figure 1is a side elevation of a pile forming wire, and its controlling heddle,embodying the main features of my present invention;

Fig. 2 is a fragmentary perspective view, greatly enlarged, of thepivotal portion of the pile forming wire and its controlling heddle;

Fig. 3 is a horizontal section thereof, taken approximately on the line8-3 of Fig. 2;

Fig. 4: is an elevational view of one end of the controlling heddleillustrating the interlacing of the ends of the pair of members of whichthe heddle is composed;

Fig. 5-is a vertical section thereof, taken approximately on the line 55 of Fig. 4; ma

Fig. 6 is a perspective view thereof.

Referring to the drawings, in the particular embodiment of my inventiontherein shown, 10 is the pile forming wire proper, upon the free endportion 11 of which the pile or loop is formed, in the manner wellunderstood by those skilled in the art. In some instances the uppermarginal edge of the enlarged portion 11. at the end thereof, issharpened for the purpose of forming a cut pile fabric which alternativearrangement is also well known to those skilled in the art.

The other end of the pile forming wire 10 xis pivoted. as at 13 to thecontrolling heddle 1 1. which comprises a pair of flat, thin strips ofmetal 15, arranged side by side with the pivotal end ofthe pile formwire10 disposed therebetween. At the place of the pivotal attachment of thepile forming wire 10 to the controlling heddle 14, each of the thin,fiat strips of metal or wire 15 comprising said heddle 14 is providedwith a boss 16 extending inwardly (See Fig. 3)., the inner surfaces ofthe bosses 16 abutting against each other to thereby form a relativelylarge pivot for the aperture 17 at the end of the pile forming wire 10.The bosses 16 are formed in the flat strips or wires 15 by formingthemetal inward, so that there is thereby left a depression 18 in theouter surface of each of the strips 15. The bosses 16 are centrallyperforated for the passage of a rivet 19, the heads 20 of which arepositioned within the depressions 18 in the outer surfaces of the strips15, as above mentioned, so that there will be no parts projecting beyondthe outer surfaces of the strips 15. a

The ends of the strips 15 are provided with suitable mortises formounting the same in the harness frames of the loom. The ends of thestrips 15 are preferably interlaced by making the mortise 21 of onestrip longer than the mortise 22 of the other strip and of sufficientwidth to permit the other strip to pass therethrough, as illustrated inFigs. 4, 5 and 6 of the drawings.

By the foregoing arrangement, there will be provided a pile forming wireand heddle for controlling the same in which the pivotal connectionbetween the pile forming wire proper and its supporting heddle will besimple in construction yet efhcient for its intended purpose, beingcharacterized by the absence of projecting parts on the side surfaces ofthe strips coinprising the heddle, which projections would interferewith the tree passage of the Warp threads as the sheds are successivelyformed, the pivotal action being at all times free-and provided with alarge bearing surface, thereby insuring less likelihood of destructionin use.

Having thus described the nature and characteristic'features of myinvention, What a I claim as new and. desire to secure by Lett ersPatent is:

w '1. A pile forming Wire, and a controlling heddle to which one end ofsaid pile forming Wire is pivotallyconnected, said heddle comprising twostrips of thin, flat netal or Wire having the pivotal end of the'pileforming Wire disposed therehetvveen, each of said stripshaving the metalstamped or pressed inward toforin a boss and means for securing saidbosses to each other whereby said bosses will form a pivot for the endof the pile forming Wire. 1

2. A pile forming Wire, and a controlling heddle to Which one end ofsaid pile forniing ivireis pivotally connected, said heddle comprisingtwo strips of thin, flat metal or Wire having the pivotal end of thepile forming WlIG'CllSPOSEt therebetween,each of said str'ipshavingthemetal stamped or pressed inward to form ahose, said bosses coacting toform a pivot for the end of the pile formingWire, said bosses beingcentrally apertured, and a rivet passing through the apertures in saidbosses for securing the same to eachother.

8. A pile forming Wire, and-a controlling "heddle'to which one end ofsaid pile forming -wire is pi'votally connected, said heddle comprising'tWO StIupS O ht-lnn, fiat metal or Wire having the pivotal end of thepile forining Wire disposecttherehetween, each or said str'ipsfhavingthe inetalstarnped or pressed inward to form a 'boss fsaid hossescoacting to form a pivot for the endo'fthe :p'il'e form- 'lieads of saidrivet he ing Wire, said bosses being centrally aperstrips hating themetal stain ied "or pressed inward to form aboss, said bosses coactingto form a pijvot for the 'end of the pile forming Wire, said bossesbeing centrally apertu'red, a rivet passin 'g therethrough, the

heads of said "rivet being positioned within the depressed portions-inthe outer surfaces of the strips comprising the heddle, :and the enos ofthe strips corripri'sing the heddle'loeing interlaced.

In testimony whereof, I have hereunto signed my name.
